以下是 STM32ZET6 PWM 初始化代码的基本框架,你可以根据自己的具体需求进行修改:
```
#include "stm32f2xx.h"
void PWM_Init(void)
{
// 使能 GPIO 时钟
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);
// 配置 GPIO 引脚为 PWM 模式
GPIO_InitTypeDef GPIO_InitStructure;
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_x;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;
GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;
GPIO_Init(GPIOx, &GPIO_InitStructure);
// 使能 TIM 时钟
RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE);
// 配置 TIM 基本参数
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
TIM_TimeBaseStructure.TIM_Prescaler = ;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseStructure.TIM_Period = ;
TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
TIM_TimeBaseStructure.TIM_RepetitionCounter = 0;
TIM_TimeBaseInit(TIMx, &TIM_TimeBaseStructure);
// 配置 PWM 模式和占空比
TIM_OCInitTypeDef TIM_OCInitStructure;
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
TIM_OCInitStructure.TIM_Pulse = ;
TIM_OC1Init(TIMx, &TIM_OCInitStructure);
// 使能 TIM
TIM_Cmd(TIMx, ENABLE);
}
```
其中,需要根据具体的 GPIO 引脚、TIM 定时器和 PWM 参数进行相应的修改。
